The latest in a string of ISIS videos to feature child soldiers features a boy, about ten years of age, brandishing a rocket-propelled grenade and threatening to behead President Obama unless the United States submits to the Islamic State.

As the UK Daily Mailreports, the video is titled “A Message to the Dog of Rome Obama,” which implies Obama is a servant of the Vatican engaged in a literal Crusade against the Islamic State. This is terribly unfair to President Obama, who has spoken out against the Crusades on many occasions, as when he memorably lectured Christians not to get up on their “high horses” over Islamist atrocities.

ISIS has a lot more on its mind than challenging Obama’s knowledge of 11th-century history, however. After flashing some Islamic State gang signs, the child soldier tells Obama, “If you think your soldiers will enter the land of the khalifah and pollute it with their filth, you’re dreaming. Wake up from your sleep and pay the jizya in submission before the swords of the khalifah reach you and cut your filthy head.”

The jizya is a religious tax imposed by Muslims upon subjugated non-believers, while khalifah means “caliphate,” the title ISIS claims for its empire.

The video clip closes with the image of a motorboat racing across the water, which the Daily Mail takes to imply “the threat of terrorists slipping into Europe hidden among the hundreds of thousands of migrants.”

Previous ISIS videos have pictured child soldiers with guns and suggested they were undergoing military training, and taking part in the execution of prisoners. The Islamic State refers to these children as “Cubs of the Caliphate.” A March article by the Jerusalem Poststated that ISIS had recruited at least 400 children in Syria over the previous few months—sometimes encouraging parents to send their kids to training camps, other times seizing the children without their parents’ consent.
